IMPROVEMENT IN TRANSPARENT DOOR-PLATES.

Specification forming part of Letters Patent No. 157,724, dated December15, 1874; application filed October 31, 1874.

ing, forming a part of this specification, in'

Which Figure 1 is a front elevation, and Fig. 2 a rear elevation, of myimprovement.

Like letters of reference indicate corresponding parts in the differentfigures of the drawmg.

My invention relates to that class of doorplates which are composedwholly or in part of glass; and consists in a novel construction andarrangement of the parts, by which the plate is adapted for both day andnight use, and also for a door or cover to a letter-box, as hereinaftermore fully set forth and claimed.

The extreme simplicity of my invention renders an elaborate descriptionunnecessary.

In Fig. 1, A represents asection ofthe door to which the plate isapplied, and B the escutcheon or frame, which is constructed of met-a1,and is held in place by means of the studs 0 c, Fig. 2. These studs arehollow and threaded, as shown at d 01, being designed to receive screwsfrom the inside of the door. The setting or frame of the name-plate O'isprovided with lugs g g, and is hinged to the escutcheon B by means ofthe projections D I) and rod f. A spring, E, is coiled around the rod,one end of said spring resting upon The plate itself is composed ofglass, or other transparent or translucent material, set in a metallicframe, and is designed to bear a name and the number of the street, asshown.

It will be obvious that in the nighttime a door-plate of this charactermay be readily illuminated from the interior. of the house, renderingthe name and number inscribed thereon perfectly visible; also, that whenarranged as described, it will serve as a selfclosing door to aletter-box.

I am aware that a letter-box or letter-box escutcheon for attachment todoors has been used, having a hinged metallic cover; and I do not,therefore, claim the same, broadly, or when in and of itself considered;but

What I claim is- 1. As a new article of manufacture, the name-plate andletter-chute cover combined, constructed of the retracting glass plate0, mounted on the metallic frame X, and hinged to the escutcheon B bymeans of the lugs D D g g and rod f, the latter being provided with aspring, E, substantially as described.

2. The escutcheon or plate B, provided at its inner ends with studs 0 0,having internal screw-threads cl d, for the purpose described.
